Abstract
A method for controlling a derailleur in low battery remaining capacity includes determining whether a remaining capacity of a first battery of the derailleur is smaller than or equal to a first derailleur battery threshold. When the remaining capacity of the first battery is determined to be smaller than or equal to the first derailleur battery threshold, at least one of gear positions of the derailleur is invalided and non-selectable by the derailleur.

A method for controlling a derailleur in low battery remaining capacity, the method comprising:
- determining whether a remaining capacity of a first battery of the derailleur is smaller than or equal to a first derailleur battery threshold;
- when the remaining capacity of the first battery is determined to be smaller than or equal to the first derailleur battery threshold, at least one of gear positions of the derailleur is invalided and non-selectable by the derailleur;
- wherein after the at least one of the gear positions of the derailleur is invalided and non-selectable by the derailleur, the method further comprises:
- determining whether the remaining capacity of the first battery is smaller than or equal to a second derailleur battery threshold, wherein the second derailleur battery threshold is smaller than the first derailleur battery threshold;
- when the remaining capacity of the first battery is determined to be larger than the second derailleur battery threshold, the derailleur is allowed to be shifted to another one of the gear positions that is not invalided and non-selectable by the derailleur.

A method for controlling a derailleur in low battery remaining capacity, the method comprising:
- determining whether a remaining capacity of a battery of a shift lever is smaller than or equal to a first lever battery threshold;
- when the remaining capacity of the battery is determined to be smaller than or equal to the first lever battery threshold, at least one of gear positions of the derailleur is invalided and non-selectable by the derailleur;
- wherein after the at least one of the gear positions of the derailleur is invalided and non-selectable by the derailleur, the method further comprises:
- determining whether the remaining capacity of the battery is smaller than or equal to a second lever battery threshold, wherein the second lever battery threshold is smaller than the first lever battery threshold;
- when the remaining capacity of the battery is determined to be larger than the second lever battery threshold, the derailleur is allowed to be shifted to another one of the gear positions that is not invalided and non-selectable by the derailleur.

A method for controlling a derailleur in low battery remaining capacity, the method comprising:
- determining whether a remaining capacity of a first battery of the derailleur is smaller than or equal to a first derailleur battery threshold, and determining whether a remaining capacity of a second battery of a shift lever is smaller than or equal to a first lever battery threshold;
- when the remaining capacity of the first battery is smaller than or equal to the first derailleur battery threshold, or the remaining capacity of the second battery is smaller than or equal to the first lever battery threshold, the shift lever does not send a gear shifting signal to the derailleur, or the derailleur is unresponsive to the gear shifting signal sent by the shift lever, and then the method further comprises:
- determining whether the remaining capacity of the first battery is smaller than or equal to a second derailleur battery threshold and determining whether the remaining capacity of the second battery is smaller than or equal to a second lever battery threshold, wherein the second derailleur battery threshold is smaller than the first derailleur battery threshold, and the second lever battery threshold is smaller than the first lever battery threshold;
- when the remaining capacity of the first battery is determined to be larger than the second derailleur battery threshold, and the remaining capacity of the second battery is larger than the second lever battery threshold, the derailleur is allowed to be shifted to another one of gear positions that is not invalided and non-selectable by the derailleur.
